Ping a host to check connectivity

Read-only
What do risk levels mean?
Read-only
Inspects state without changing anything.
Low risk
Reversible with a routine follow-up command.
Medium risk
Changes state; undo path documented.
Destructive
Deletes or overwrites; confirmation required.

Sends a fixed number of ICMP echo requests to a host to confirm basic network reachability and measure round-trip latency.

networkpingconnectivitylatency

Parameters

Hostname or IP address to ping.

Number of echo requests to send.

Commands

Send a bounded number of echo requests and report latency statistics

ping -c 4 <host>

Verification

ping -c 1 <host>

A reply line with a time value confirms the host is reachable; 100% packet loss means it is not.

Undo

Not undoable

This recipe only sends echo requests and changes nothing.

Pitfalls

  • Many hosts and firewalls drop ICMP, so no reply does not prove the host is down; test a TCP port as a second signal.
  • Name resolution failures surface here as "unknown host" — that is a DNS problem, not a connectivity problem.
  • The verification command uses macOS/Linux syntax; on Windows use "ping -n 1 {{host}}".
